    Sorry but this has to be said. The word is teleScopic. As in, it teleScopes. I know this makes me a word nazi but I do mean it in all niceness.

    i will post later some sound and vidéos. But if you are a didgeridoo player it sound like any good didgeridoo but you can tune it as you want and chage the size of the diameter. I will post too the way i play it as a low frequency acoustic generator or other way in the experimental music field.
